The common causes of itchy oral palate are environmental irritation, recurrent oral herpes simplex and allergic rhinitis.
1. Environmental irritation: If the oral and nasal cavities inhale a lot of dust, dust mites or irritating gases, these substances can stimulate the peripheral nerves of the epiglottis mucous membrane and nasal mucous membrane, causing itchy epiglottis and nasal cavities.
2. Recurrent oral herpes simplex: If the mucous membrane of the upper jaw of the mouth is infected by the herpes simplex virus, which triggers recurrent oral herpes simplex, the upper jaw of the mouth will itch under the stimulation of the virus.
3. Allergic rhinitis: If nasal inhalation of allergens causes allergic rhinitis, and because the nasal cavity is connected to the oral cavity, the palate of the mouth will also be stimulated by histamine, which will cause itching of the palate of the mouth.
If the upper jaw of the mouth itchy, must go to the hospital in time to find out the cause of the disease, and actively cooperate with the professional doctor’s treatment.
